本文旨在研究长输管道防腐层状况不开挖检测的常见技术问题,并提出解决技术措施.长输管道定期检验外腐蚀外检测方法中,防腐层状况不开挖检测是主要的检验内容,采用PCM(Pipeline Current Mapper)检测技术,其检测质量的高低决定了防腐层破损处的检测效果和长输管道运行的安全.文章在分析长输管道PCM检测重要性的基础上,探讨长输管道PCM检测中普遍遇到的问题,结合多年实践操作经验及国家相关法规,提出针对性的解决方案和处理方法.
This article aims to investigate the common technical issues regarding the non-excavation detection of the anti-corrosion coating condition of long-distance pipelines,and propose solutions and technical measures.Among the external corrosion detection methods for the regular inspection of long-distance pipelines,the non-excavation detection of the anti-corrosion coating condition detection is a major aspect.The PCM(Pipeline Current Mapper)testing technology is used.The quality of its detection determines the detection result of damaged areas in the anti-corrosion coating and the safety of long-distance pipeline operation.On the basis of analyzing the significance of PCM detection for long-distance pipelines,this article explores the prevalent problems encountered in PCM detection of long-distance pipelines.In combination with years of practical operation experience and relevant national regulations,targeted solutions and treatment approaches are proposed.
